Question

A (-2,-5) is a glide reflection wear the translation is (x,y) is x+7,y and the line of reflection is y=2 what is A’

Answer 1

point A' is (5, 9)

Explanation:

A (-2,-5) is a glide reflection wear the translation is (x,y) is x+7,y and the line of reflection is y=2

A is (-2,-5)

a glide reflection wear the translation is (x,y) is (x+7,y)

7 is added with x, so add 7 with x value -2 on A(-2,-5)

(-2+7, -5)

(5,-5)

Reflection is y=2

So we need to find the difference of y values of point (5,-5) and y = 2

2-(-5) = 7

So we move 7 units up from y = 2. y=2+7 = 9

x value remains the same x=5

Hence point A' is (5, 9)
